SPECIFICATION forming part of Letters Patent No. 629,419, dated July 25, 1899.

Application niet. septemterzs, 189s. serial No. 692,083. In@ modem To all whom it may concern: l

Be it known that I, CHARLES AW. BOLTON, a citizen of the United States, residing at Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented a certain new and useful Improvement in tVindows, of which the followingisa specification.

My invention relates to'a new and useful improvement in windows, and has for its object to so construct a window and the sashes thereof as to provide for. the turning of the sashes upon pivots without .interfering with the raising and lowering of the same in the ordinary manner.

A further object of my invention is to provide means for firmly locking each sash in its vertical position and rendering the sliding joints weatherproof.

AV still further object of my invention is to so arrange the devices that when the sashes are closed they will not rattle; and a still further object of my invention is to so connect theweight cord or bands with the weights as to prevent the cramping of the sashes in their revolving movements.

With these ends in view this invention consists in the details of construction and combination of elements hereinafter set forth and then specifically designated by the claims.

In o rder that those skilled in the art to which this invention appertains may understand how to make and use the same, the construction and operation will now be described in detail, referring to the accompanying drawings, forming a part of this specification, in which* 4 Figure 1 is a vertical section of a Windowframe, showing the sashes in elevation and illustrating the manner of balancing said sashes by the weights and cords or bands, also showing the locking-strips in position; Fig. 2, an enlarged view of a portion of the side of one of the sashes, the locking-strip being removed to expose to view one of the cambarrels for actuating the locking-strip; Fig.'

Fig. 12 is a section of a portion of an ordib nary window, showing lmy improvement applied thereto; and Fig.'13, a View similar to Fig. 6, showing the manner of drawing the locking-strip against the Window-sash when the cam-slot is not formed in the barrel, as shown in Fig. 12.

In carrying'out m yin vention as here shown, A represents the window-casing, having its inner vertical sides grooved, as indicated at o, b, c, and d, and within the grooves ct are fitted to slide the carrier-strips B. Between these strips is pivoted the lower sash C, so that it may be turned horizontally or at any angle between the perpendicular and the horizontal, and D are locking-strips arranged against the inner face of the side sash, so as to move. into engagement with the groove l), and when these strips are in this engagement, as shown in Figs. l and 3, the lower sash will be held against any swinging movement, but will be `free to move vertically with the carrier-stri ps B, both these carrier-strips and the locking-strips serving to guide the sash in this movement. The locking-strips are secured against the sash and operated in the following manner: Camharrels F. are fitted in the side rails of the sash so as to revolve therein by holes being -drilled in the sash, and the plugs F are' fitted within the barrels ICO so that the latter may turn without affecting said plugs, the locking-strips being attached to the plugs by the screws G, passed through the strips and threaded into the plugs, as clearly shown. An escutcheon-plate H is secured upon the face of the sash side so as to be iiush therewith, there being one of said plates for each of the barrels, and the pin -projects inward from each of the escutcheonplates, passing into the cam-slot J, formed in the barrel, so that when the latter has turned u ponits axis this escutcheon-plate, being stationary, will cause the barrel to move in or ou t, as the case may be. If the barrel is moved' in by its rotation, the locking-strip -will be carried therewith on account of its connection with the plug, this movement of the screw G being permitted by the slot K, while the barrel is permitted to revolve without interfering with the screw by the slot L formed therein, as will be readily understood. Each of the barrels has a handle M formed thereon, turned at right angles thereto, so as to yfacilitate the manipulation of the barrel, and thus the actuation of the locking-strips.

The cam-slots in the barrels should be of such shape that when each pair of barrels on which the locking-strip is attached has been properly operated the locking-strip will be forced into the groove b and there held in such manner as to permit the raising or lowering ofthe sash without the displacement of the locking-strip. YWhen the locking-strip is moved into the groove b, it is advantageous that it at the same time be drawn tightly against the face of the sash, and this is accomplished by the eccentricity of the hole in the barrel in which the plug is located. When the handle M of each barrel is turned outward, the locking-strip will have been retracted, and this position of the handle also brings the thin side of the barrel, which is indicated at cl', next to the locking-strip, and this permits a slight movement of the plug toward the inner face of the sash, which will free the locking-strip from pressure against the faceof the side; but when the handle M is turned to a vertical position the thick side (indicated at e) will be brought next the face of the sash, and thereby draw the plug inward, which in turn will draw the lockingstrip tightly against the face of the sash.

Each of the carrier-strips has attached to its upper end a rope, band, or chain N,Which passes upward, the one upon the left side in Fig. l passing over the pulley O and downward to the weight P,which is attached thereto, while the rope upon the right side of the sash passes first over the pulley O and then along through the top of the casing over the pulley O and downward to the weight P, to which it is attached. This arrangement suspends the entire lower sash from the weight P, and as both sides of the sash are attached to this weight through the ropes it follows that the sash will not cramp, since at all times it is evenly drawn upon both sides in counlli tei-balancing, and should the strain to move it upward or downward be exerted upon one side alone the weight will be actuated, and through it the opposite side will be caused to move in unison. This is of considerable advantage in my improvement, since the carrier-strips are not rigidly secured to the sash and therefore would otherwise have a tendency to move out of unison, which would result in the cramping ofthe window-sash when revolving.

In order that the sash when adjusted to swing upon the pivot-screws Q may be held in the desired position, I provide a latch R, which is pivoted to the edge of the sash, said sash being cut away, so as to permit this latch to lie Hush therewith. A pin or screw S is secured in the strip B and the latch provided with notches for engagement with this screw, as clearly shown in Fig. ll, and when these notches are thus engaged the sash will be firmly held at its adjusted angle, as will be readily understood; but when the sash is secured in its vertical position this latch is turned int-o the cut-away portion of the sash, as shown in Fig. 9, thus filling this space and preventing the ingress of air at this point.

lAs a further means of binding the windowsash tightly within the frame when closed the lower portion of the groove,in which one of the carrierstrips B slides, is deflected, as indicated at T, so that when this strip reaches this portion of the groove it is crowded into a groove of the window-sash, as clearly shown in Fig. 9, thereby jamming said sash against the opposite side of the window-frame, and thus rmly holding it against rattling.

In case the carrier-strips are not used a stationary deflected strip may be placed at the lower end of the groove, so that when the sash is closed it will likewise be jammed and held against vibration. 4

Under some circumstances it will be found advantageous to dispense with the carrierstrips, and when this is done the construction shown in Fig. 1l will answer the purpose of said strips, the result being accomplished by the pivot-screw U being passed through the eve U', which is attached to the weight-cord U2, the head of the screw falling within the groove in the windowfframe for guiding the sash, or a shoe may be used to attach the cord, through which'the screw may pass, and when this construction is utilized a stop-block Vis secured in eachof the grooves in the window-frame in order that when the sash is lowered the heads of the screws U will rest upon this stop, thereby permitting the swinging of the sash upon the pivot-screws without liability of cramping or the sash becoming displaced. This arrangement is also advantageous when the sash is balanced in the usual manner-that is, by separate weights for each side of the sash.

It will of course be understood that the upper sash in any case will be arranged in the same manner as the lower sash and withV IOO IIO

-connection is made between the barrel and the sash, so that when the locking-strip is to be retracted the handle of the barrel is grasped and turned, so as to relieve the locking-strip of its pressure against thesash, when the barrel is thereafter pulled inward toward the center'of the sash, drawing with it the locking-strip. The barrel may then be again turned upon its axis, so as to draw the plug inward by reason of the yeccentricity of the bore of the barrel, as clearly shown in Fig'. 13, the full lines being the position of the locking-strip and barrel when saidv strip is drawn against the sash and the dotted lines representing the position of thesev parts when the locking-strip is loosened so as to be moved back and forth. This, as will be seen, accomplishes the same result as the arrangement before described, requiring an eXtra hand movement to draw the locking-strip from the groove when being retracted or foroing it within the groove when the reverse is heilig accomplished. The pulleys O and O are attached to the upper side of the board M, which is loosely fitted within the upper y portion of the window-casing, the only means for holding it in place being the downward draft of the weights P and the sashes; but in practice it has been found that this is entirely sufficient, and a great advantage is had by this arrangement of the board and the pulleys, since no strips or fasteners are needed, and the board may be readily removed at any time, carrying with it the pulleys for repair or other purposes. Another advantage of this arrangement is that the pulleys are entirely out of sight, and yet easy access may be had thereto, and they may be readily placed in position when finishing the window and hanging the sash.

In practice I have found that a window fitted with my improvement is exceedingly simple of operation and may be used as the ordinary window for raising andlowering, and yet when it is to be cleaned the sashes thereof. may be swung upon their pivot-points, so as to gain access to both sides thereof without having to lean from the window, and thus avoid the possibility of accident; also, when the maximum ventilation is needed the swinging of the sashes upon their pivot-points and their proper adjustment will give the full open space of the window, and thefaot that the sashes may be adj ustcdat various angles will greatly facilitate the ventilation of a room, and they may be so adj usted as to shed water,

thus avoiding having to close the window on account of rain. Y

It is obvious that my improvement may be used in connection with transo'ms, in which case the locking-strips would serve the twofold purpose of forming a tight joint when the transom is closed and of locking the same against being opened from the outside, and

vthe advantage of my improvement when thus applied is rthat the stop-beads do not have to be divided to allow for the swinging of one half ofthe transom in while the other half swings out. Having thus fully what I claim as new and useful iss p Al. In combination with a window, the inner sides of which are grooved, carrier-strips adapted to travel within certain of said grooves, a sash fitted to each pair of carrierstrips, a locking-strip arranged against the face of each side of the sash, said strip adapted to run in one of the grooves of the windowframe, two or more barrels set in each of the sides of the sashso as to turn therein, said barreis having cam-slots and cross-slots, a plug loosely fitted in each of the barrels, a screw passing through the locking-strip, the crossslotin the barrel and threaded into the plug, an escutcheon-plate for each of the barrels secured iush against the side, and a pin projecting from the escutcheon-plate into the described my invention,-
